How are the various quantities measured? (continued)
This can be accessed by default under Meas… Trend and is used to display
the evolution of the quantity measured with respect to a fixed time scale >88s;
the vertical scale may be automatic or manual (range selection).
This mode is available on all main functions measured.
This mode indicates that the value
displayed is relative to a reference value.
It is available for the following
measurement functions:
V, Hz, Ohm, clamp, capacitance,
temperature, and current.
Using the internal technical specifications
of the multimeter, the SPEC mode
directly displays the tolerance on the
measurement in progress, with no need
to look for it and calculate it.
This mode is very useful for the
metrology of the instrument.
It gives access to the secondary measurements of the main measurement: a
maximum of 3 secondary measurements can be displayed. Refer to the Table of
secondary measurements in the Appendix.
This mode is available in MEAS… MEAS+ for the following measurement
functions: V, Hz, Ohm, and current.
The MATH function y = Ax + B (A and B configurable in Setup Math Coeff
A and B) enables the user, measuring an arbitrary physical quantity in:
- Volts ( e.g.: process 0-10V or high-voltage probe)
- Amperes (: 4-20mA current loop or current clamp)
- Frequency (: measurement of flow rates, speeds of rotation)
- Ohms (: resistive position sensor)
to convert it and assign the appropriate unit so as to obtain a direct reading of
the original quantity on the instrument.
It is available via Meas… MEAS+ MATH under the following measurement
functions: V, Hz, Ohm, and current.
